According to the utility model, under the precondition that the volume of the coil is not increased, higher intensity of magnetic field can be obtained to improve the on-off capability of the contact structure in a vacuum circuit breaker.
Description
Technical field
The utility model relates to a kind of structure of contact terminal, particularly a kind of structure of contact terminal that is used for vacuum interrupter.
Background technology
Pressure field during at present vacuum circuit-breaker is widely used in, and in 126kV and above high pressure and superhigh pressure field SF
6Circuit breaker accounts for the empery status.But SF
6Gas is one of six kinds of main greenhouse gases that limit in the United Nations Framework Convention on Climate Change Kyoto Protocol, and its greenhouse effects of the earth coefficient is CO
223900 times of gas, the life-span reaches 3200 in the atmosphere.With SF
6Circuit breaker is compared, and vacuum circuit-breaker has environmental friendliness, product reliability height, little, the product technology performance advantages of higher of maintenance workload, and therefore developing high-pressure vacuum breaker is to reduce SF
6A kind of very good and selection of putting.At present in the vacuum circuit-breaker, general 1/4th circle coils, 1/3rd circle coils, 1/2nd circle coils of using of the coil of structure of contact terminal, because the restriction of conductive path length, magnetic field intensity also are not easy to improve, therefore be difficult to improve the connecting-disconnecting function of structure of contact terminal at vacuum circuit-breaker.And extension coil length simply causes winding volume excessive easily, is not suitable for the use in vacuum circuit-breaker.
The utility model content
The purpose of this utility model is, a kind of vacuum interrupter one circle coil structure of contact terminal is provided.It can obtain higher magnetic field intensity to improve the connecting-disconnecting function of structure of contact terminal in vacuum circuit-breaker under the prerequisite that does not increase winding volume.
The technical solution of the utility model: a kind of vacuum interrupter one circle coil structure of contact terminal, comprise conducting rod, coil, reinforcement and contact, it is characterized in that: described coil comprises a conduction cup, conduction cup top has two grooves, groove cuts out two crownings in conduction cup top portion, having link slot at an end of groove links to each other with middle groove one end along conduction cup middle part circumference Rotate 180 °, in the groove other end have down link slot and conduct electricity the kerve of bottom of cup and link to each other, at the bottom of kerve runs through glass.
In the above-mentioned vacuum interrupter one circle coil structure of contact terminal, described contact is the CuCr alloy, and has two straight troughs.
In the aforesaid vacuum interrupter one circle coil structure of contact terminal, the crowning at described conduction cup top docks with the contact plane, and the straight trough on the contact aligns with the end that groove is not opened link slot.
Compared with prior art, the utility model is by offering various grooves on the conduction cup, make coil become double-deck two lobes, the one circle coil, under the prerequisite that does not increase winding volume, increased loop length, promptly increase conductive path, improved magnetic field intensity, thereby improved the connecting-disconnecting function of structure of contact terminal in vacuum circuit-breaker.Realizing that the utility model can reduce the volume of structure of contact terminal under the identical connecting-disconnecting function, the miniaturization development of vacuum circuit-breaker is being had positive effect.
